Splicing Screen Border Weakening via Prism Light Deflection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The splicing of LCD screens to create a larger display area is hindered by visible borders that disrupt image continuity and integrity, and existing methods to reduce these borders, such as using transparent plates with V-shape grooves, increase thickness and cost while only partially mitigating the issue.
Innovation Solution
A splicing-screen border weakening structure featuring a transparent solid element with a first prism structure on its light-ray exiting surface, which deflects light rays exiting from the edge display area, allowing them to exit at different angles and reducing the visibility of the border, without covering the entire screen and maintaining a thin profile.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a transparent plate with V-shape groove is arranged on the surface of each display screen to weaken the border, then the border effect is weakened, but the thickness of the splicing screen increases and the cost increases
Solution Approach 1:
The patent applies local quality by placing the transparent plate with V-shape groove only at the border area between display screens rather than covering the entire screen surface. This localized application weakens the border effect where it is needed while minimizing the increase in overall thickness and reducing material usage compared to full-coverage solutions.
Solution Approach 2:
The patent introduces a new dimensional approach by creating a three-dimensional V-shape groove structure on the transparent plate. This groove depth dimension allows light rays to be deflected at multiple angles, weakening the border effect more effectively while using less material than a uniformly thick transparent plate would require.
2Object-affected harmful factors
If a transparent plate with V-shape groove is arranged on the surface of each display screen to weaken the border, then the border effect is weakened, but the cost increases
Solution Approach 1:
By limiting the transparent plate application to only the border regions between display screens rather than covering the entire screen, the patent reduces material consumption and manufacturing costs while still achieving the border weakening effect where it is most needed.
Solution Approach 2:
The patent applies partial action by using transparent plates only at the necessary border areas rather than applying them to the entire display surface. This partial coverage approach achieves sufficient border effect reduction without the excessive material and cost requirements of full-coverage solutions.
3Object-affected harmful factors
If the V-shape groove has sufficient depth to weaken the border, then the border effect is weakened, but the thickness of the transparent plate must increase
Solution Approach 1:
The patent utilizes the depth dimension of the V-shape groove to achieve border weakening without requiring increased overall plate thickness. The groove creates a three-dimensional light-deflecting structure that accomplishes the border effect reduction function while maintaining a thin overall profile.
Solution Approach 2:
The patent segments the transparent plate structure by introducing V-shape grooves that divide the plate into different depth zones. This segmentation allows light to be deflected at multiple interfaces within the groove structure, achieving effective border weakening without requiring the entire plate to be thick.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration effectively cancels or weakens the border effect at various visual angles, reducing the thickness and cost of the splicing screen while maintaining a seamless visual experience across the display area.
Implementation Method 1
a first prism structure is at least arranged at a position corresponding to the inner area of the light-ray exiting surface, a light ray exits from the edge display area of the display screen and enters into the outer area of the transparent solid element, and a part of the light ray is deflected by the first prism structure of the light-ray exiting surface of the transparent solid element

AI summary
A splicing-screen border weakening structure includes a transparent solid element through which a light ray is able to penetrate. The transparent solid element includes a fixing surface which is used for fixing to the border and a light-ray exiting surface which is opposite to the fixing surface, and further includes an inner area which is opposite to the border and an outer area which is opposite to an edge display area of the display screen. A first prism structure is at least arranged at a position corresponding to the inner area of the light-ray exiting surface. A light ray exits from the edge display area and enters into the outer area of the transparent solid element, and a part of the light ray is deflected by the first prism structure of the light-ray exiting surface and exits from an inner area of the light-ray exiting surface.
